Growing cilantro indoors hydroponically in Winter

Winter growing cilantro indoors hydroponically

So am trying this growing cilantros indoors seeds that I bought in amazon, am trying the Kratky Method with Dyna-gro 7-9-5 solution and see the results. I place the seeds on a strainer just barely touching the solution, in 7 days little roots started to emerge and I can see lots of them. My temperature in my porch is 68 deg I cover them with aluminum foil and let them rest. So far looking good and I can wait till I taste them in my pico de gallo sauce.

This is 1 weeks old roots are emerging

Under the strainer roots are popping out trying to reach the nutrients
